DRAIN ONNEQTI N- This invention relates to improvements in drainconnections.

The present invention contemplates the provision of improved meansforconnect- ,ing the drain opening of a shower stall or the like tothe-drain pipe or trap disposed therebelow.

One of the objects of the'present invention is to provide improved meansof the character referred to wherein the strainer plate may be readilyplaced and secured in position over the outlet or waste opening in'thebottom of the shower stall without the necessity of rotating the plate,as heretofore, the improved means providing for proper fitting togetheror alignment of the parts in the event that the waste opening in thebottom of the stall is not lined up exactly with the drain pipe ortrapbelow. 7

Other objects and advantages will hereinafter appear.

For the purpose of illustrating the invention, one embodiment thereof isshown in the drawings, in which Figure 1 is a sectional view, line 11 inFig. 2. and

Fig. 2 is a plan view.

In the drawings, 10 represents the floor or bottom of a shower stall,lavatory or the like provided with the usual outlet opening 11, a drainpipe 12 internally threaded at its upper end, as shown, being disposedbelow floor 10 with its threaded end co-axial with the floor opening,the edge 13 of the floor opening overhanging this end of the drain.

An externally threaded collar lt is threaded into the end of drain 12flush therewith, and is provided with the pair of inwardly directeddiametrically opposite lugs 15.

A strainer plate 16 provided with dis charge openings 17 is disposedabove floor 10 and fitted over the floor opening with its edge 18overlapping and engaging the edge 13 of said opening. The plate 16 isfurther provided with the depending annular flange 19 coaxial with andspaced from the edge 13 of opening 11 and extending downwardly intodrain pipe 12 and terminating short of lugs 15. The strainer plate isheld in position by bolts 20 extending downwardly therethrough andthreaded into lugs 15, whereby the edge 18 of the plate is held in takenon the 'two bolts 19 and without the necessity of turning or rotatingthe plate whereby ,the

edge :18 thereof'w'ould scrape over the underlying e'dge13of the fiooropening and thus remove at this point any protective coating ofpaint-with which the floor might be provided, the bolts 20 acting tosecurely clamp plate 16 iii-position and to provide a tight jointbetween the edge 18 thereof and the edge'13 of opening 11. In the eventthat the bottom or floor 10 is not set up.

exactly in alignment with drain 12, there is sufficient play of bolts 20in the openings 21 in plate 16 to permit sutlicienttilt-ing of the boltswithout disturbing the snug fit between plate 16 and the floor 10.

Furthermore, in the event of slight leakage or seepage of water betweenthe floor edge 13 and plate edge 18, the water will be directed into thespace between edge 13 and flange 19 and will thence flow into the drain12 with the water flowing into the latter by way of outlet openings 17The flange 19 acts as a guard to direct the water issuing from openings1'7 into the drain and to prevent any of the water from finding its wayupwardly to the edge 13 of opening 11 and causing possible corrosion atthis point as well as at the threads by which collar 14 is held inposition in the end of the drain.

When it is desired to remove plate 16 to provide floor 10 with a newprotective coat of paint, or for other reasons, it is merely necessaryto remove bolts 19, after which plate 16 may be readily lifted out ofposition. In the improved construction there is no threaded connection,as in constructions used heretofore, between the part overlapping andfitting tightly upon the floor at the outlet opening thereof, which partin the present construction is the strainer plate 16, the latterperforming the double function of providing the outlet or drain openings17 I been shown and described, but of course various changes may be madesuch as in the size, shape and arrangement of the parts withoutdeparting from the spirit of the invention or the scope of the claims.

The invention claimed is:

-1. In combination with a floor provided with an opening, and a draininternally threaded at one end and disposed below said floor with saidend coaxial with the floor opening, the edge of the floor openingoverhanging said end of the drain, of an eXternally-threaded collarthreaded into said end and provided with inwardly directed lugs, astrainer plate disposed above said floor and fitted 'over the flooropening with its edge overlapping and engaging the edge of said opening,and bolts extending d0wnwardly throughsaid plate and threaded into saidlugs to hold said plate in' position with its edge in tight engagementwith the underlying edge of the floor" opening.

:2. In combination with a floor provided with an opening, and adraininternally threaded at one end and disposed below said floor with saidend coaxial with the floor opening, the edge of the floor openingoverhanging said end of the drain, of an externally-threaded collarthreaded into said end substantially flush therewith and provided withinwardly directed lugs, a strainer plate disposed above said floor andfitted over the floor opening with its edge overlapping and engaging theedge of said opening, said plate being provided with a depending annularflange coaxial with and spaced from the edge of said opening andextending into said drain and terminating short of said lugs, and boltsextending 'downwardlv through said plate and threaded into said lugs tohold said plate in position with its edge in tight engagement with theunderlying edge of the floor opening.

In witness whereof, I hereto aflix my sig nature.
